I have made a pcb for four TO220 diodes including snubber network with only a capacitor or a capacitor+resistor. The diodes can mounted on heatsinks and the pcb has 70 um copper, good for 50-80 A. Room for PHE450 heavy duty caps from EVOX RIFA. Note also that I use the best audio connector in the world, the patented Wago from Germany.http://home.swipnet.se/~w-50719/hifi/rfb01

I had also been looking for a board that would allow me to mount all for the diodes on a single heatsink in a single plane. Peter Daniel made some for his A75 to Aleph5 conversion, but I've never seen them available commercially.

Hi peranders,

would You mind to explain why this is the best (audio) connector?

I have used this connectors in a project 5 years ago but wasn`t aware that they should be "so" good. I`ve simply choosed them because they`re avaible in nice different colours and because they fit in this particular application so well.
Usually I rather shy away from spring contacts and feel more comfortable using solid srew-type connectors but this is just because of my gut-feeling and actually there might be some good reasons to use those Wago.
